[2 marks]Describe how to multiply two n-degree polynomials together in O(n logn) time, using the Fast Fourier Transform (FFT). You do not need to explain how FFT works – you may treat it as a black box. In this part we will use the Fast Fourier Transform (FFT) algorithm described in class to multiply multiple polynomials together (not just two). Suppose you have K polynomials P1, . . . , Pk so that degree(P1) +···+ degree(PK) =S (i)[6 marks]Show that...

A3: This question illustrates how different bases for spaces of polynomials can help solv- ing mathematical problems. In particular, we look at the use of Lagrange polynomials for polynomial interpolation. Let be the space of polynomials of degree at most two.

At the horizontal intercept x = -3, coming from the (x+3) factor of the polynomial, the graph passes directly through the horizontal intercept. The factor (x+3) is linear (has a power of 1), so the behavior near the intercept is like that of a line - it passes directly through the intercept. We call this a single zero, since the zero corresponds to a single factor of the function. At the horizontal intercept x = 2, coming from the (x...
